<3-6. content audiovisual start to process again>

Start to process is to open the state that the audiovisual of content as illustrated using Figure 14 is interrupted again again for content audiovisual The process of the audiovisual of beginning content.Start to process is carried out according to the flow chart of Figure 10～Figure 13 having been described above again for content audiovisual.

Hereinafter, for the start to process again of content audiovisual, with reference to Figure 10～Figure 13 flow chart while with concrete example Explanation.

Premise as present treatment is it is assumed that the content that audiovisual is interrupted is content A of C01 for content ID.With regard to content A, Hypothesis is configured to, and which kind of the audiovisual form by " 2D ", " stereoscopic_MVC " can audiovisual.Moreover, it is assumed that again Recorded in available_play_mode key element in the reproduction control information that existing control information server 12 sends " 2D ", Both " stereoscopic_MVC ".

Assume that to the interruption of audiovisual the transcriber 3 by device id is D01 has reproduced content, audiovisual form is stereoscopic_MVC.The number of seconds of audiovisual when assuming that the audiovisual of content A is interrupted is 3600 seconds.

Assume being initially not transcriber 3 again and pass through transcriber 4 and carry out of audiovisual of content A.In transcriber 4 In it is assumed that not carrying out the audiovisual of content A before this starts again.The user of transcriber 3 and transcriber 4 is identical, ID For U01.

Assume that starting customer management information in the storage part 33 of portal server 11 for the tightly front record again is shown in Fig. 4 State.

Based on these premises, illustrate along Figure 10～13 below.In addition, herein in relation to Figure 10 used in explanation ～Figure 13 is illustrated in detail.Thus, again whole steps is not explained, suitable according to importance degree Explanation is simplified.

First, in the S11 of Figure 10, the user of transcriber 4 uses user operation portion 90 input content of transcriber 4 Guide look display request (S11).User operation portion 90 accepts content guide look display request, by content guide look display request to browser Processing unit 88 notifies.

Content guide look is sent request and sends (S12) to portal server 11 by browser processing unit 88.In portal server In 11, communication processing section 31 receives content guide look and sends request, exports to data processing division 32.Data processing division 32 carries out content Guide look documenting processes (S13).

Here, in the content guide look file that transcriber 4 obtains, in the content tab of content A of having interrupted audiovisual In PlayPosition, set the number of seconds of the audiovisual (3600) of transcriber 3.

The browser processing unit 88 of transcriber 4 is based on content and has a guide look of file, makes display that content name is had a guide look of display (S202 of S15, Figure 12).Now, with regard to content A, show, using icon, the situation that audiovisual is interrupted.

User selects content A (S203) as reproduced objects content.Browser processing unit 88 is by the reproduction with regard to content A Object content information stores (S204).

Now, as reproduced objects content, select to set content A (in S205 being) of PlayPosition, thus clear Device processing unit 88 of looking at makes display processing portion 86 show as the reproduction being by from the starting, which kind of the selection being further continued for reproduction The reproducing positions of picture select picture (S206).

Now, user carries out the user input selecting to be further continued for reproducing.

Browser processing unit 88 is further continued for reproducing (in S207 being) due to have selected, so as reproduced objects content information PlayPosition, will as the PlayPosition in content tab 3600 storage (S208).

And, the MetaFileURL in reproduced objects content information is read (S16) by browser processing unit 88, and it is right to carry out Reproduction control information in this URL sends request (S17).

Reproduction control information with regard to content A is sent (S18) to transcriber 4 by reproduction control information server 12.

Browser processing unit 88 receives reproduction control information from reproduction control information server 12.And, extracting start will Plain (S301), extracts the available_play_mode key element (S302～303) in reproduction control information.

And, browser processing unit 88 makes display show as making user from being documented in reproduction control information Choosing in executable audiovisual form (" 2D ", " 3D (stereoscopic_MVC) ") in available_play_mode key element The audiovisual form as shown in Figure 15 selecting the picture of 1 selects picture (S304).

In addition, in fig .15, in transcriber 4 from the content guide look file that portal server 11 receives Audiovisual form (such as " 3D (stereoscopic_MVC) ") acquiescence described in the PlayMode of content tab holding A is carried out by force Adjust.

Here, suppose that user selects 2D (S305～306).

Browser processing unit 88 preserves " 2D " in the X-Request-Play-Mode head that HTTP-GET asks (S307), additional X-TimeSeekRange head, sets 3600 (S309, S310) as value.

And, the content that browser processing unit 88 carries out to presentation content server 13 asking by HTTP-GET point Send out request (S20 of Figure 10).

The part of from the starting 3600 seconds is distributed with backward transcriber 4 by presentation content server 13 with regard to content A, with Just can be with 2D audiovisual.

Transcriber 4 from presentation content server 13 receive content A, carry out from the starting 3600 seconds partly later again Existing (S22).

By more than, in transcriber 4, by content A from the audiovisual form (3D being used by transcriber 3 (stereoscopic_MVC)) it is changed to other audiovisual form (2D), can be from then being regarded by transcriber 3 audiovisual Listen.

In addition, with regard to the starting again of audiovisual of content A, to be illustrated by the example that transcriber 4 is carried out, but with regard to Situation about being carried out by transcriber 3 is also same with described above.

<4. variation>

This concludes the description of the embodiment of content providing system for the present invention but it is also possible to put forward the content of illustration Deform as follows for system, the present invention is not limited to represent that such content provides system in the above-described embodiment certainly System.

(1) in the above-described embodiment, in order to transcriber 3 being notified with previous audiovisual form from portal server 11 and Using html file, but as long as previous audiovisual form can be notified to be sufficient for.

For example, as carrying out reproducing the function starting it is also possible to define as launchIPTVContentEx () There is the new function notifying the previous function of audiovisual form.

This new function is implanted to be had a guide look of in the BML file of file generated as content, distributes to the purchase by content Buy pressing of button or reproduction button etc. and start the button of the reproduction of content.Notified previous audiovisual form is reproducing dress The audiovisual form putting middle acquiescence when starting again as audiovisual uses, or for determining using selecting be shown to audiovisual shape Give tacit consent in the button of audiovisual form on state selection picture and focus is placed on which.

LaunchIPTVContentEx (inputStringcontent_uri, inputStringret_uri, InputNumberstart_npt, [inputStringlicense_id ,] inputStringplay_mode)

Here, content_uri represents the URI of reproducing control meta file corresponding with the content of reproduced objects.ret_uri Represent the URI of the BML file of display after content reproduction terminates.Start_npt represent content reproduction time position (from The number of seconds having started of content).The time location being provided by independent variable start_npt specified by transcriber, and presentation content is taken The data is activation of business device 101 request content.License_id represents the mandate ID of the mandate using when reproducing.play_mode Represent the audiovisual form of content.Play_mode records " 2D ", " stereoscopic_MVC " as value.In play_mode it is In the case of " 2D ", represent content as 2D image reproduction, in the case of " stereoscopic_MVC ", represent content As 3D image reproduction.

In addition it is also possible to select picture BML file to show the audiovisual form of Figure 15, described in BML file being, The button being selected as 2D image reproduction, the button being selected as 3D image reproduction execute in the case of being pressed respectively LaunchIPTVContentEx () function.

Specifically, described in BML file it is being, holding in the case of the button being selected as 2D image reproduction is selected The value of row independent variable play_mode is the launchIPTVContentEx () function of " 2D ".In addition it is recited as, be selected as The value executing independent variable play_mode in the case of the button of 3D image reproduction is selected is " stereoscopic_MVC " LaunchIPTVContentEx () function.

Additionally, in this case as well, it is possible to BML file is configured to, with the use being stored in portal server 11 There is focus on the button of audiovisual form audiovisual of the final audiovisual homomorphosis of family management information.That is, BML file is configured to, In the case that final audiovisual form is " stereoscopic_MVC " so that execution play_mode value be " 3D " There is focus on the button of launchIPTVContentEx () function, BML file is configured to, be " 2D " in final audiovisual form In the case of so that execution play_mode value be " 2D " launchIPTVContentEx () function button on have Focus.

(2) in variation (1), define and using the function notifying previous audiovisual form LaunchIPTVContentEx (), but as long as notify previous audiovisual form to be sufficient for.For example, it is also possible to audiovisual form is led to Cross reproduction control information to specify.In the case, add the default_ shown in Fig. 7 as one in reproduction control information Play_mode key element.

Default_play_mode key element records " 2D " or " stereoscopic_MVC " as parameter value.

Additionally, it is also possible to select which of 2D image and 3D image to be prestored to reproduction acquiescence in transcriber In device.

Additionally, default_play_mode key element may not be notifies previous audiovisual form, but represent service The audiovisual form of the acquiescence of this content of the settings such as supplier.

Additionally, default_play_mode key element can also be the display that content delivering system 2 possesses according to transcriber Ability sets.That is, content delivering system 2 can also be, if transcriber is the display capabilities with 3D, conduct The value of default_play_mode key element and set 3D, if transcriber is the display capabilities without 3D, conduct The value of default_play_mode key element and set 2D.

(3) in the above-described embodiment, select picture as audiovisual form, as long as available_play_ will be documented in The selection that executable audiovisual form in mode is shown on display, carry out audiovisual form by user input is just permissible, But as long as audiovisual form can be selected to be sufficient for.For example, it is also possible to by specific button by the inferior action predetermining Lai User is made to select audiovisual form.

(4) in the above-described embodiment, in order to from transcriber 3 to presentation content server 13 notify audiovisual form and X-Request-Play-Mode head described in HTTP-GET request, but as long as can know in presentation content server 13 Other audiovisual form is sufficient for.

For example, between transcriber 3 and presentation content server 13, in HTTP-GET request, there is no X- It is also possible to prespecified specify " 2D " for regarding as in the case of Request-Play-Mode head.Accordingly, for HTTP-GET request it can be ensured that with only content being reproduced with 2D, do not correspond to and with the addition of X-Request- The interchangeability of the old system and device of the extension of Play-Mode.

(5) in the above-described embodiment it is assumed that send image be MVC image in the case of, in X-Request- In the case that Play-Mode is " 2D ", presentation content server 13 enters in distribution to be about to comprise the TS bag removal that subordinate regards Process and distribute, but as long as can send do not comprise subordinate depending on image data be sufficient for.For example, it is also possible to prepare in advance not wrap Containing subordinate depending on image data and be sent to.Send thereby, it is possible to avoid regarding the subordinate not used in transcriber side, energy Enough communication bandwidths saving use.

(6) in the above-described embodiment it is assumed that the application according to user such as device id is in the distribution contract conclusion of content By content distribution, business uniquely distributes, but as long as the equipment that can uniquely identify is sufficient for.For example can also using IP address or MAC Address etc..

(7) in the above-described embodiment it is assumed that transcriber 3 carry out content audiovisual, in have no progeny, different in device id Transcriber 4 start the audiovisual of this content again in the case of, whole from can take with regard to this content in transcriber 4 1 audiovisual form is selected but it is also possible to carry out when audiovisual starts again limiting audiovisual form using device id in audiovisual form The control of optionies.

For example, it is also possible to be, for content, there is ability, the conduct that 3D shows in the transcriber 3 as fixed terminal When the transcriber 4 of panel computer terminal does not have the ability that 3D shows and only has the ability that 2D shows for this content Under, it is controlled in transcriber 4, select not showing 3D audiovisual in picture with the audiovisual form showing when starting audiovisual again Optionies or 3D audiovisual can not be selected.

(8) in the above-described embodiment, in the available_play_mode key element in reproduction control information, as The audiovisual form that can take with regard to content and record " 2D ", " 3D (stereoscopic_MVC) ", lead to transcriber 3 and 4 Know, but audiovisual form is not limited to " 2D ", " 3D (stereoscopic_MVC) ", as long as representing with regard to content visually Display form be sufficient for.

For example, audiovisual form can also represent each angle of the content with regard to multi-angle performance.Additionally, audiovisual form is respectively Represent the multiple programs carving distribution at the same time.

In the case, in the available_play_mode key element in reproduction control information, as shown in figure 16, make Enumerate " View1 ", " View2 " of audiovisual form that expression can be taken with regard to content etc. for one.View1, View2 ... point Do not represent each angle or each program.

Additionally, audiovisual form can also be resolution.In the case, the available_ in reproduction control information In play_mode key element, as shown in figure 17, as the audiovisual form that can take with regard to content, enumerate " SD as one (Standard Definition)”、“HD(High Definition)”、“4K”、“QVGA(Quarter Video Graphics Array) " etc..Here, so-called 4K, represents 4000 × 2000 points about of resolution.

Additionally, in the above-described embodiment, illustrate add in ERI available_play_mode key element or The example of default_play_mode key element, but as long as can notify the content same with them to be sufficient for.For example, it is also possible to Add the key element using other titles.Additionally, using " 2D " and " stereoscopic_MVC " as the value of each key element, but Can be using the other values (" 3D " etc.) of the same content of expression.

Above explanation is that the available_play_mode key element in reproduction control information is carried out, but with regard to Used in communication between above-mentioned transcriber 3 and presentation content server 13, X-Request-Play-Mode is also same Sample.

(9) in the above-described embodiment, transcriber 3 and 4 asking to presentation content server 13 " reproduction of content, Start (distribution starts) again ", in the case of " reproduction of content is interrupted, is stopped " using HTTP, but as long as can ask " content Reproduce, start again ", " reproduction of content is interrupted, stopped " be sufficient for.

For example, it is also possible to use RTP (Real time Transport Protocol) as data communication, as it Control protocol and use RTSP (Real Time Streaming Protocol).In addition, RTP is defined by RFC3550, RTSP by RFC2326 defines.

In RTSP, Streaming Media reproduce in use (a) SETUP, (b) PLAY, (c) PAUSE, (d) TEARDOWN each Method.

SETUP is to indicate that the resource going out to the streaming of server guarantees the method with session start.

PLAY is the method the sending of media data that instruction is carried out by the resource being guaranteed by SETUP.Internal Hold and use in the case of being reproduced.

PAUSE is to indicate the method sending stopping not discharging server resource and temporarily flowing.Content is temporary Stop, stop both middle uses of the situation of (reproduction terminates).

TEARDOWN is the method for the end of the instruction release of resource and session.

Here, PLAY replaces the HTTP-GET in above-mentioned embodiment to ask and use.

PAUSE replaces the content in above-mentioned embodiment to reproduce end notification and use.

SETUP does not have especially corresponding method etc. in the above-described embodiment, uses before PLAY.

TEARDOWN does not have especially corresponding method etc. in the above-described embodiment, in the situation terminating the reproduction of content Lower use.

Hereinafter, record the example of each method (request, response) of (a) SETUP, (b) PLAY, (c) PAUSE.With regard to TEARDOWN, due to the place especially not changed with the regulation of RFC2326, so omit record.

Here, in order to describe the audiovisual that can utilize in the content in the response of each method of SETUP, PLAY, PAUSE Form, carries out adding the extension of extension header X-Available-Play-Mode.In X-Available-Play-Mode In, record represent 2D and 3D both " 2D3D ", represent 2D " 2D ", represent 3D " 3D " certain.
